how to visualize vector/raster from directly from GRASS database? I am building webGRASS. for that I linked GRASS GIS all libraries to my application without any wrappers.. Now I can execute any grass command online. But for rendering I use OpenLayers. I want to change OpenLayers and use a WPaintWidget to draw raster and vector data
I can make this happen in this way [1] call d.vect which will call v.out.ogr and create a gml file --> display gml on OpenLayers.Map Now I want to reduce the overhead by spawning different process like d.vect --> v.out.ogr --> gml -->openlayers I need rendering this way [2] Read GRASS data directly from database (points/line/polygon for vector and image pixel values from GRASS raster format so the chain will be GRASS Raster data --> (image pixel values) MyNewMapCanvas GRASS Vector data --->(points/lines/polygons) MyNewMapCanvas The reason behind my need is that on web it will increase speed and efficiency when we read data from GRASS database directly All I want to do GRASS GIS core language C/C++ to make a web application it is possible because I am linking my website with required grass libraries (libgrass_*) Any help will be greatly appreciated.. -- Regards, Mohammed Rashad K M M.S.
